Hello, everyone!

We have an SL64 board with an XFP optical module. According to the product documentation, the output optical power ranges from 0 dBm to 4 dBm. But the actual value is -5 dBm.

What's the reason for this?

hi
the output power from 0-4 usually idicates that you are using Le type (Le-64.2) .
but if the out power is less than the threshold
;
1- make sure that the XFP is not faulty , through management make sure of the out optical power , if it is not  between 0-4 , so maybe the XFP needs cleaning or may be you should change the patchcord you use .
2- make sure of the specifications of the XFP and that it is single mode , 1550nm , the distance not less than 60km .
3- make sure that you use single mode patch cord not multimode .

Hello!
If the output optical power is constant, the possibility of the power supply is low. There is a high probability that the connection is loose or the hardware is faulty. You can perform a comparison test by replacing the slot, board, and optical module.
